Frequently Asked Questions
Q: What Crown equipment models use the CR 87402 bearing?
A: The CR 87402 is a deep groove roller bearing designed for Crown model 6600 manual pallet jacks. This bearing supports wheel rotation at the load wheel or steer wheel position. The model 6600 is a standard manual pallet jack line, so confirm your specific truck serial number and wheel location before ordering.
Q: What are the specifications for the CR 87402 deep groove bearing?
A: The CR 87402 is a deep groove ball bearing with specific bore diameter, outer diameter, and width matched to the Crown 6600 axle assembly and wheel hub. Typical specifications include hardened steel races and steel balls suitable for manual pallet jack loads up to 6000 pounds. Verify bore size and outer diameter before ordering to ensure correct fitment.
Q: What are the symptoms of a failing CR 87402 bearing?
A: Signs of bearing failure include excessive wheel play or wobbling at the affected wheel, squeaking or grinding noise during operation, or a wheel that does not rotate freely when the pallet jack is lifted. The wheel may drag or bind if the bearing races are damaged. Replace the bearing immediately if these symptoms appear to prevent further equipment damage.
Q: How long does the CR 87402 bearing last in normal pallet jack service?
A: A well-maintained CR 87402 bearing typically provides 5 to 10 years of service life in a standard warehouse environment. Lifespan depends on load cycles, floor condition, bearing lubrication, and whether the truck is used indoors on smooth floors versus rough or outdoor surfaces. Contamination from dirt or lack of lubrication shortens bearing life significantly.
Q: Are there equivalent bearing part numbers for the Crown 6600 model 6600?
A: The CR 87402 is the Crown OEM bearing for the 6600 model. Generic deep groove ball bearings with the same bore and outer diameters may fit physically but may not meet Crown load rating or durability specifications. Order the CR 87402 to ensure proper performance and warranty compliance on Crown 6600 manual pallet jacks.
